corporation-of Delaware v Application oembevr 19, 1931. serial m1569319 15 claims. (01.105-195) This invention relates to railway rolling stock and consists in a novel spring equalizing arrangement particularly adapted for six and eight wheelA vehicle trucks.

Six wheel trucks are usually provided with either one or two spring systems on each side, each system including semi-elliptic. springs resting on the journal boxesand intermediate equalizing bars pivotally supporting the truck frame.l These equalizing bars have been provided with single or double pivots, but it has been found that Y in the former case the truck is unstable and has a tendency to tilt longitudinally, while in the lat` ter case increased stability is accompanied by decreased'lexibility and poor riding qualities of the truck.

In certain spring arrangements, transverse equalizers have been used which are usually hung from the ends of springs 'on' opposite sides of the truck and are pivoted vrto a transverse transom vmember oi the` frame intermediatev `the sides.l

However, this type of transverse equalizer requires heavy construction of the equalizing* bar andtransom which undesirably increase the Weight and.A cost of the truck.

The main object of the present invention 'is to provide improved spring equalizing means for a truck which will be more flexible than is the case where the equalizer bars have double pivotal connections with the frame, and will be more stable than where' the bars have single pivots.

Another object is to provide transverse equalization which will permitv the use oi lighter construction than has heretofore been possible.

These objects and others are attained in the structure illustrated in theaccompanying draw-1 v horizontal arms of the bell crank supported di- Figure2 is a vertical longitudinal section taken on the line 2-2 of Figure 1.

Figure 3 is an end View of the truck..

Figure '4 is a View corresponding with Figure 2 but illustratinga modification.

' Figure 5 is a view similar to Figures 2 and 4 and illustrating still another modification.

Figure 6 is a detail vertical transverse section taken-substantially on the line 6-6 of Figure 5.

In Figures lto 3, the invention is illustrated as embodied ina six wheel tender truck including box section wheel pieces 1, end sills 2, transcms 3, a bolster 5 including the usual center plate, and pedestals 7 mounting journal boxes 8. Brackets 9 project from each end of thewheel pieces 1 `for truck.

rand coiled-spring 37 seated against the under-V Mounted onl the respective journal boxes 8 are semi-elliptic springs 11, 12, and 13. Spring 13 has hangers 14 at each end which are anchored to the 'wheel piece by pins 15. Intermediate springs 11 and 12 is an equalizing bar 16 pivotally 60 secured to the Wheel piece by a single pivot 16a and supported at' its ends by hangers 17a on the adjacent ends oi the springs 11 and 12. The right hand end ofspring 12 is anchored to the wheel piece by means of the hanger 17 and a hanger 18, 65 l to bev described hereafter, depends from the left hand end vof spring 11V and projects through an opening 18a in the undersideof the vwheel piece. The spring arrangements on opposite sides of the truck are similar. l' l 1 Brake hanger brackets 9 on the left end of thetruck frame are provided with extensions 19 pivotally mounting bell cranks 20 which are rockable in a plane extending transversely of the YThe lower end of thel upright arm of each bell crank is secured to a transverse rod 21 and the horizontal arm of each crank isoperatively connected with the endpof a lever 22 which is pivoted to the adjacent pedestal 7 by a pin 23 and which is supported by a gib 24 80 located near the lower extremity of hanger 18. Opening 25, 'receiving gib 24, is large enough to provide for varying the size ofggib to adjust the spring system.V

A The truck frame is supported on three separately anchored spring systems, i. e.the single springs on eachside of the right end of the truck and Ythe transversely vequalized system. The levers 22 are for the purpose of spacing the bell crank and transverse rod from the brake rig ging. These levers; could beV eliminated and the rectly from hangers 18 without affecting the operation y,of the spring system. Figure 4 illustrates a modiedform of the invention'as applied to an eight wheel truck. The left-hand portion of the spring system on each side of the truck, including springs 26 and 27, equalizers 28, and the transverse connecting elements, yis the same asin Figure 2. Springs 29 and 30, mounted on the right hand'pair of journal boxes, (not shown) carry hangers 31 at their adjacent ends which ,support an equalizer 32 having a singlepivotal connection with the wheelr piece. The inner-.end of spring 29 is anchored to the frame through a hanger 33 and the outer end of spring 30 mounts a hanger 34 which depends through an Vopening 35 in the underside oi the Wheel pieceand carries a spring seat 36V one end of the other pair having supporting connections toV said frame, and means cooperating with the remaining hangerof said other pair for equalizing said last mentioned pair with the corresponding pair on the other side of the truck, said means comprising bell cranks pivoted to said frame and rockable transversely of the truck, oppositely disposed arms of said cranks being operated by one of said last-mentioned hangers on each side of the frame, and a transverse rod connecting the other arms of said cranks.
